BRAKE PEDDLE GOES TO FLOOR.

Suzuki Other

Hy guys I have a 1984 susuki sj410, mileage unknown. Car still runs great though. The problem is the brake peddle goes to the floor, unless you pump them once or twice. I have had the master cylinder rebuilt. Lines replaced, we have bled everything there is to bleed including the master, twice. I am desperate for any help or advive you can give me. Thank you Tyler
